title: [Regional irrigation of the pericardium in children].
abstract: OBJECTIVE
  To investigate the irrigation of both fibrous pericardium and the parietal layer of serosal pericardium in children.
  
  
  METHODS
  The cadavers of 10 children of both sexes, under the age of one. In this study we adopted the regional divisions described by DI Dio, which considers a plane between the two phrenic nerves that divides the areas of pericardium into ventral and dorsal regions. We also refer to these regions as antephrenic and retrophrenic respectively. In addition, we consider the inferior pericardium to be that portion of pericardial sac related to the diaphragm.
  
  
  RESULTS
  The pericardium ventralis was more frequently irrigated by branches of the following arteries: thoracicae internae dextra and sinistra, pericardiacophrenica dextra in 9 cases; pericardiacophrenica sinistra in 8 cases; and less frequently, by branches of the arteriae phrenicae inferiores dextra and sinistra, epigastrica superior sinistra, thimica, rami thimici of the a. thoracica interna dextra, and rami thimicus and esophagealis of the a. subclavia dextra. The pericardium dorsalis was more frequently supplied b the following arterial branches: bronchiales in 9 cases; esophagealis of the aorta in 8 cases; and in a frequency inferior than 4 cases, we observed the following arteries: thyroidea inferior sinistra, intercostalis suprema, pericardiacophrenicae dextra and sinistra, subclavia sinistra, coronariae dextra and sinistra, phrenicae superior and inferior sinistra, thoracica interna dextra, intercostales posteriores primae dextra and sinistra, truncus costocervalis and rami esophageales of the a. gastrica sinistra. The pericardium inferior was irrigated by branches of the arteriae phrenicae inferiores dextra in 10 cases and sinistra in 9 cases.
  
  
  CONCLUSIONS
  Analysis of the results demonstrated that similar behavior in the pericardium regional irrigation offers a standard for intervention in the pericardium.
